Claim Evidence Reasoning

During the first month of class I really worked hard with my students to teach the scientific method, inductive, and deductive reasoning.  About 1/3 just don't get it and that has really bothered me.  I was wondering what to do to help them when I discovered this morning while talking to a colleague (we both get to school about 90 minutes early each day) that all my students have been taught to think in terms of Claim, Evidence, Reasoning!   All that is is looking at the scientific method and deductive reasoning from the other side of the process.  Whereas the premise+premise=conclusion and  phenomenon-->hypothesis-->experiment-->theory steps take the scientist from virgin observation of nature through to a published journal article, the CER process gives the science student a system for evaluating the published work of scientists, including movies I might show in class and their own textbook!  So that is what we started doing today.  MUCH FUN!!!  I hope this helps me reach the 1/3 who never quite understood my lessons on Aristotle deducing the sphericity of the earth.

Introduction and meeting the needs of diverse students

I began this blog for another course (MAT670, I think) but am now updating it for MAT671. I am about to be fifty years old and I am embarking on a new career.  in the past I have been a soldier, a bookkeeper, an advertising executive, a paralegal, and a real estate investor.  For the last two years I have been working as a substitute teacher. My education has kind of been all over the place.  I was homeschooled until I joined the U.S. Army at age 17.  They trained me to be a chaplain assistant, a personnel clerk, and a combat lifesaver (kind like a low level medic.  All it really meant was that I could start IVs, treat for shock, and give morphine).  The army also sent me to The Air Assault School . About a year before I got out of the Army I took a class in sociology at Austin Peay State University and discovered that I enjoyed academics, so when I was discharged from the army and moved to California I started taking classes at De Anza College....

I've seen the philosophies and I think I can do better (a paper written for NU)

Having read the descriptions of the four educational philosophies (Cohen, L. 1999)  I was, at first, equally attracted to Perennialism (Munoz, K. 2013) and Essentialism (Borst, T. 2014), but after reading more in depth about each of them I think I have decided that Perennialism is better than Essentialism, in so far as each was presented by Munoz and Borst. I have been a fan of Mortimer J. Adler for decades, having first read his book Six Great Ideas in 1991.  Later, I found out about his great books program at the University of Chicago when I became interested in the economics program there.  I read a lot of the books on that list though I never bought the whole set edited by Adler and his friend Robert Hutchins. A few years after that, with my own children I used many of the childrens books recommended by Adler; The Blue Fairy Book (Lang, 1965), Treasure Island (Stevenson, R. 1993), and The Three Musketeers (Dumas, 1993) became favorites of all my sons. ...
